The first thing you see is the box and packaging. It's part of the experience. It's impressive and a suggestion of what is about to come. I wasn't disappointed. Every piece was first class. Heavy machined brass, stainless steel, and aluminum make up the parts of this steam engine and boiler. The assembly instructions meet the same high standards. Assembly takes less than two hours. The result is a working boiler and steam engine that drives a generator lighting a street lamp. Speed can be controlled by the steam valve or the reverse lever. It's fun to build and operate as well as it's a good-looking piece for display. All in, a good experience and I recommend these products to anyone interested.
